Question

I'm running Premiere V14.1 on Mac OS High Sierra. The audio runs fine during playback on the timeline but after render out to video files, it is out of sync by a lot. The sequence matches the render files output, anyone has any suggestion? Thanks.

Did resetting the preferences and workspaces work?

I have changed the Audio Hardware, Default Input to No Input. Playback disabled Mercury Transmit. I notice the Premiere direct render at the beginning is sync but later is out of sync with the 15s clip. The AME is the worse, sound is out of sync at the beginning till end. Let me know what needs to be done

Does it do that both with and without GPU acceleration?

Does it do it both with direct export and export through AME?

The files are rendered with AME V13.1.5 with Metal GPU acceleration. Thanks

Try resetting the preferences:
https://community.adobe.com/t5/Premiere-Pro/FAQ-How-to-reset-trash-preferences-in-Premiere-Pro/td-p/8236158

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

Please use the free MediaInfo and post a screenshot the properties of your media in tree view:

If the file is variable frame rate, which although Adobe says it will support, many users are having issues with VFR.

Use Hand brake to convert to constant frame rate:
